Abstract Electron-induced reactive processing (EIReP) recently has appeared as an advanced processing technology to modify several polymer compounds at melt state by its spatial and temporal precise energy input. In the present work, an attempt was made to prepare a compatible blend from polar polyamide 6 (PA6) and non-polar polypropylene (PP) using EIReP without any chemical crosslinking and chemical additives. EIReP modified blends were prepared at different doses (5, 10 and 20 kGy) and dose per revolutions (3, 6 and 12 kGy/rev) while keeping constant the values of mass ratio (PA6/PP 50/50 w/w), electron energy (1.5 MeV), rotor speed (60 rpm) and temperature (230 °C). EIReP process parameters-morphology-property relationship of this blend was studied. Interestingly, co-continuous morphology of the blend was converted to droplet-matrix morphology after EIReP whether PA6 was continuous phase. Influence of dose and dose per revolution on the DMT modulus (Derjaguin-Muller-Toporov) at different phases of the blends was also measured and analyzed using advanced PeakForce Quantitative Nanomechanical Mapping atomic force microscopy (PF QNM AFM) technique. Improved nano- and macroscopic properties of EIReP modified blends were originated from the properties of the continuous matrix phase, electron-induced branching and also from the reduction of domain size of PP phase with increased dose.

聚酰胺 6/聚丙烯共混物的电子诱导反应加工：形态和性能

摘要 电子诱导反应加工 (EIReP) 最近作为一种先进的加工技术出现，通过其空间和时间精确的能量输入来改性熔融状态下的几种聚合物化合物。在目前的工作中，尝试使用 EIReP 由极性聚酰胺 6 (PA6) 和非极性聚丙烯 (PP) 制备相容共混物，而无需任何化学交联和化学添加剂。EIReP 改性共混物以不同剂量（5、10 和 20 kGy）和每转剂量（3、6 和 12 kGy/rev）制备，同时保持质量比值（PA6/PP 50/50 w/w）不变，电子能量 (1.5 MeV)、转子速度 (60 rpm) 和温度 (230 °C)。研究了该混合物的 EIReP 工艺参数-形态-性能关系。有趣的是，无论 PA6 是否为连续相，EIReP 后共混物的共连续形态都转化为液滴-基质形态。还使用先进的 PeakForce 定量纳米机械映射原子力显微镜 (PF QNM AFM) 技术测量和分析了剂量和每转剂量对混合物不同相的 DMT 模量 (Derjaguin-Muller-Toporov) 的影响。EIReP 改性共混物的纳米和宏观性能的改善源于连续基质相的性能、电子诱导支化以及 PP 相的畴尺寸随着剂量增加而减小。还使用先进的 PeakForce 定量纳米机械映射原子力显微镜 (PF QNM AFM) 技术测量和分析了剂量和每转剂量对混合物不同相的 DMT 模量 (Derjaguin-Muller-Toporov) 的影响。EIReP 改性共混物的纳米和宏观性能的改善源于连续基质相的性能、电子诱导支化以及 PP 相的畴尺寸随着剂量增加而减小。还使用先进的 PeakForce 定量纳米机械映射原子力显微镜 (PF QNM AFM) 技术测量和分析了剂量和每转剂量对混合物不同相的 DMT 模量 (Derjaguin-Muller-Toporov) 的影响。EIReP 改性共混物的纳米和宏观性能的改善源于连续基质相的性能、电子诱导支化以及 PP 相的畴尺寸随着剂量增加而减小。
